Why not? Planes spend most of their time at cruise, so I figure if they can reduce cruising fuel consumption by downsizing the engine, it'd help a fair amount.
However it does have me wondering why they don't just use a turbocharged engine. Same effect, no? (Smaller displacement engine = better FE under light load; but turbo for power when needed.)
